November 4, 200421 yr Hi Ben.. Sorry..still trying to find out about SHoei sizing compared to Arais..no luck so far. Woman in the Arai shop here reckoned the sizing for a trials lid is the same as for an Arai ROAD full face lid. BUT...doesnt work for me. I'm a size 57.58 in an Arai road lid...and a 59.60 in an Arai trials lid. ANyway..will keep trying on the Shoei/Arai sizing thing
November 5, 200421 yr I've worn Shoei and Arai MX and street helmets for years. They fit very similar. The Shoei tends to be a firmer fit, while the Arai more a plush fit. Head shapes are very similar (as this is usually an issue for me). If you take a Medium Shoei, the a Medium Arai should be good. Edited November 5, 200421 yr by JTT
